SOLAR SYSTEM

Detailed explanation-1: -The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.

Detailed explanation-2: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

Detailed explanation-3: -The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.

Detailed explanation-4: -The Earth was formed about 4.6 billion years ago, that’s 4, 600, 000, 000 years ago. It was formed by collisions of particles in a large cloud of material.

Detailed explanation-5: -The Sun and its family of planets formed when a cloud of dust and gas condensed 4.6 billion years ago. Several hundred million years after the Earth took form, an outer crust developed.
